Purpose: This research was conducted to identify major factors that influence competency for nursing students in basic nursing skills. Method: Data were collected by questionnaires from 290 first year students in one college of nursing. The instrument tools included motivation for admission to nursing, concern about fundamentals of nursing, perceived importance of fundamentals of nursing, level of active participation in fundamentals of nursing, number of times to use open Lab, Lab class satisfaction, self-efficacy, self-evaluation and student attitude. Results: There was no significant correlation between competency in basic nursing skills and motivation for admission to nursing, concern about fundamentals of nursing, perceived importance of fundamentals of nursing, or number of times to use open Lab. Competency in basic nursing skill in these students showed a significantly positive correlation to Lab class satisfaction, self-efficacy, self-evaluation, student attitude and level of active participation in fundamentals of nursing. The major factors that influenced competency in basic nursing skills for nursing students were student attitude, self-efficacy and number of times to use open Lab. These factors explained 15.5% of the variance in competency. Conclusion: Basic nursing skill practice education programs should be developed to improve self-efficacy and active participation.
